Which of the following factors did not influence the economic development of the united states

Alex787 [66]

Answer:

Strict immigration laws did not influence the economic development of the United States.

Explanation:

Though the United States adopted strict immigration laws in order to filter the unwanted immigrants from flooding the country, many others who could comply with these laws moved to the United States and contributed to its growth and prosperity.

The laws put up certain criterions that only allowed deserving people to flow in.

Thus, strict immigration laws did not directly influence the functioning of the overall economy.
